Flashcards in Reproductive System Deck (24):
1

Match these female parts to their male homologous (shared the same embryonic origin)?
Ovaries, Clitoris, Labia Majora, Vestibular Glands,

Ovaries=Testes
Clitoris=Glans of Penis
Labia majora=Scrotum
Vestibular Glands=Bulbourethral Glands

2

What are gonads?Produce what cells and hormones?

Ovaries and Testes. Produce games, Estrogen, Progesterone, Testosterone

3

What is the Perineum? What are the two areas?

Diamond-shaped area bordered by pubic symphasis, Ischial tuberosity, and coccyx.
Urogenital and Anal triangle.

4

Name the pathway of sperm.

Produces in Seminiferous tubules, Mature in Epididymis, Ductus (Vas) Deferens, Seminal vesicles,Ejaculatory duct, Prostatic urethra, Membranous urethra, spongy urethra,out Penis.

5

What is the function of the scrotum?

Provides cooler temp outside of body for sperm production.

6

What is the Raphe? Dartos muscle?

Raphe is the indentation/division of left and right testes.
Dartos muscle wrinkles skin of scrotum.

7

What is contained in the spermatic cord?

Ductus deferens, Cremaster muscle, Testicular nerve, Testicular artery, Pampiniform plexus, Lymphatic vessels.

8

What does the cremaster muscle do?

Lifts the testes.

9

Where are the sperm produces within the testes? Leaves by what into what?

Seminiferous tubules. Leaves by the efferent ductules into the epididymis.

10

What cells surround the seminiferous tubules? What cells produce testosterone?

Sertoli cells. Interstitial (leydig) cells produce testosterone.

11

When does spermatogenesis occur? Controlled by what hormones? Where do sperm learn to swim?

At puperty. Controlled by FSH and testosterone. Learn to swim in epididymis.

12

Seminal fluid is produces by what structures?

Seminal vesicles, Prostate gland, Bulbourethral gland.

13

What is semen? What is it called when released? Average ejaculation sperm count in one teaspoon?

Seminal fluid combined with sperm. called ejaculate when released. 200-500 million sperm

14

What are the three erectile bodies?

Corpora Cavernosa (2), Corpus Sponginosum.

15

Erection is under what nervous system control? Ejaculation?

Erection=Parasympathetic Ejaculation=Sympathetic

Point and Shoot

16

What is the prepuce?

foreskin.

17

What is the female anatomy anterior to posterior?

Clitoris, Urethra, Vagina, Anus.

18

UTI's are more common in which sex? Urethritis? Cystitis? Pyelonephritis?

More common in women because of short urethra and proximity to anus.
Urethritis: Inflammation in urethra
Cystitis: Inflammation in bladder
Pylonephritis: Inflammation in kidney

19

Name the parts of the ovary?

1. Tunica Albuginea (lines outside)
2. Ovarian cortex (follicles)
3. Ovarian Medulla: CT, vasculature, nerves.

20

What are the three phases of Ovarian Cycle? Days and what happens.

1. Follicular Phase (Days 1-13) FSH, LH, egg matures
2. Ovulation (day 14) Egg expulsion from ovary
3. Luteal (Days 15-28) Luteam produces hormones as if you were pregnant, then breaks down.

21

Name the uterine wall layers superficial to deep.

1. Perimetirum
2. Myometrium
3. Endometirum

22

What are the phases of the Uterine cycle? Days and what happens.

1. Menstural (days 1-5) Functional layer sloughed
2. Proliferative (days 6-14) Development of functional layer.
3. Secretory (days 15-28) Vascularization of functional layer, development of uterine glands.

23

What hormone surges are a part of pre-ovulation, ovulation, and post-ovulation?

1. Pre=Estrogen
2. LH causes ovulation
3. post=Progesterone

24

What are the stages of labor?

Cervical Dilation, Expulsion, Placental
